There's been a lot of publicity lately about a clamp down on foreign vehicles coming into the country. Driving in Thailand: Foreign tourists face strict controls it is generally agreed this is aimed at the masses of Chinese cars pouring in over the border at holiday & festival times On the Thai customs website there are 3 links to look at http://tta.customs.go.th/Announce/Summary.pdf http://tta.customs.go.th/Announce/Condition.pdf Thailand Transport Application It is still not 100% clear if this applies to motorcycles,, but my border contact today said that the situation for motorbikes is unchanged. The new rules are only being applied to cars at the moment. Sooner or later the dust will clear & we will know the score. BTW most of these cross border transport agreements have excluded motorbikes, with a separate "policy decision" being made later on how to handle the motorbikes; and then it often varies from border port to port.
